outdoor unit is an A/C only unit, R22 dry ship. Indoor may have strip heaters if your in an area that needs heat once in a while.

They may not have the proper metering device in the indoor unit.

Got a nice little mismatch here but being straight cool, probably not bad enough to affect performance that much. Efficiency could be compromised a bit. Were you in there with the old system? Was it a Payne A/C that matched the air handler? Any idea what kind of failure the old outdoor unit had?

I was here before the old system was replaced but, unfortunately, I was not able to note the specs of the system that was replaced.
All I know is that the fins of the condenser unit was at least 50% damaged when it was pelted by hail last March.
I have a pix of the old condenser.Attachment 300361
Note that the front and the left side have the same damage since that was the direction the hail was coming from.
Does that look like cosmetic damage.
At least that's how one of the AC techs described it to the property manager which she actually believed even when I showed it to her.

with tag info posted, looks like an air handler and it shows TXV as metering device.

evap, if read correctly, appears to be a size match to cond unit- 3 ton.

you definitely have an issue, but without being there and the info you posted, we can only offer educated WAGs; incorrect refrig, incorrect fan speed, improper operation of TXV, leaking duct work, etc.

Cost of a complete system check (including duct work)

I'll have to go with what all of you are recommending i.e. to hire a pro to check the whole system - duct work & all.
Since it will be coming out of my own pocket & am not expecting any reimbursement, would anyone know how much it would cost to have everything checked out by a REAL CERTIFIED PRO & not just by someone who may have been certified but does not really know what they are doing?
It's that or my electric bill goes through the roof while my family suffers.

BTW, the house I'm renting is a bungalow that has a living area of about 1600 sq ft.

Your landlord might object to you hiring outside help to look at their equipment. Or might not. Either way I would contact the landlord and express your intentions.

Providing landlord gives green light, next challenge is to find a certified, competent pro who wants to work on rental property. Contractors can be reluctant to do this because prior experience with landlords objecting or tenants not paying leaves a bad aftertaste.

In your extreme situation; if U really want help; there is some temperature data you can collect prior to getting permission to call an expert tech.

I know it seems like a lot; however, this is not difficult when U do it a step at a time & log the data. It must be done within the same time sequence to be meaningful...

All U need is a good thermometer (digital reading in tenths preferable) & and indoor Humidity Gauge

4) Need the ‘Indoor’ percent of relative humidity - in the middle of the rooms or, at Return-Air inlet grilles ___
5) Indoor Return-Air Temperature ______
Subtract Indoor Supply-Air Temperature ______ -F
Indoor temperature-split _______-F
----------------------------------------------
If U can find a turn in the small liquid line insulate the temperature-probe; get its temperature for the subcooling analysis:
Small liquid line temperature ____F

To measure return air the wet bulb temp, wrap a small/thin, wet (not dripping) piece of cloth around the probe and put it into the Return Air grille & then close to the closest Supply Air diffuser near the air handler (need air movement). Wait until the temperature stabilizes - may take a little while.
